Off-Season Storage
General Info
To preserve the sprayer intact and to protect its components, the following off-season storage program is carried out.
Before Storage
When the spraying season is over, you should devote some extra time to the sprayer.
If chemical residues are left over in the sprayer for longer periods, it may reduce the life of its individual components.
1. Clean the sprayer completely - inside and outside - as described under "Cleaning" on page 127. Make sure that all
valves, hoses and auxiliary equipment have been cleaned with a cleaning agent and flushed with clean water
afterwards, so that no chemical residues are left in the sprayer.
2. Replace any damaged seals and repair any leaks.
3. Empty the sprayer completely, and let the pump work for a few minutes. Operate all valves and handles to drain as
much water out off the liquid system as possible. Let the pump run, until air comes out of all nozzles. The rinsing tank
is also drained.
4. Protection against frost:
First complete the cleaning inside and outside the sprayer.
Pour approximately 50 litres of antifreeze mixture (e.g glycol and water), into the main tank. In the mixture, include any
remaining water in hidden places in the liquid system.
Depending on your winter temperatures, use the recommended mixture ratio in the table below:
Temperature
(°C)
-7
-12
-20
-31
-40
Turn on the pump and operate all valves and functions, operating units, TurboFiller etc., allowing the antifreeze mixture
to be distributed around the entire liquid system without leaving any unmixed water in hidden places.
Unmixed water will freeze and possibly damage the sprayer's components!
Open the operating unit main valve ON/OFF and distribution valves, so that the antifreeze is sprayed through the
nozzles as well. The antifreeze will also prevent O-rings, seals, diaphragms etc. from drying out.
The FlexCapacity pump must also be engaged and flushed.
Empty filters and boom pipes. Remember to unscrew the end plugs, as unmixed water can build up in blind pipe ends
causing a risk of a broken end plug or pipe, when the boom pipes are pressurized at the next spray job.
5. Remove the glycerine-filled pressure gauges and store them frost-free in a vertical position.
Also dismount the sensor (A) connected to the nozzle pressure
gauge after filling the antifreeze mixture, as this area is a possible
blind end that could result in frost damages.
